To all w/zom, it 77mg/ concern Be it known that l, VARNER H. CAMP,

a citizen of the United States, residing at.

Atlanta, in the county of Fulton and State of Georgia7 have invented new and useful Improvements in Attachments for Linting and Delinting Machines, of which the following is a specification.

This invention relates to means for removing and replacing the saw cylinders of cotton seed linting or delinting machines and for adjusting the mote board organization relatively to the brush cylinder and saw cylinder.

Heretoforc the operation of removing and replacing heavy saw cylinders of .cotton seed lin'ting or delinting machines required the services of two or more operatives, and it is obvious that where a great many machines are included in a battery the time .incident to the removal and replacement of the saw cylinders is considerable and is rather eX- pensive where the services of the. operatives thus employed are prevented in and about other places of a lintiiig or delinting plant. The main advantage of the improved means is that one operator may readily remove and replace the saw cylinder with a material saving in expense and time incident to such operations and without liability of injury either to the operator or thesaw cylinder.

A further advantage of the improved linting oi dehnt/ing machine is that the mote board as an .entirety or parts thereof may be readily adjusted to dispose the saine as may be desired relatively to the brush and saw cylinders to suit or accommodate any conditions, and to mote and make the lint as clean as desired.

A further advantage of the improved means or mechanism is that application thereof to linting or delinting machines when the latter are primarily constructed or to the same kind of machines that have been iii use may be readily accomplished at a comparatively small expense with a mateiial reduction in. the cost of maintaining the machines in properoperative condition.

Other advantages will be hereinafter specified, and in order to present a disclosure of the invention the accompanying drawings illustrate one preferred'embodiment of the improved means lor attachment, and m the drawings: Figure 1 is a perspective view of a linting or delinting machine with the features of the invention applied thereto. F ig.I 2 is a transverse vertical section through the machine and particularly showing the position of tlie cylinder removing means or mechanism when starting t0 lift the saw cylinder for the purpose of removing or when replacing said saw cylinder in its bearings and also illustrating the improved mote board organization. Fig. 3 is a. view similar to Fig. 2 showing the saw cylinder elevated and thrown outwardly by the improved mechanism and the breast also elevated and held by engaging means therefor. Fig. 4 is a detail perspective view of one of the cylinder lifting forks and its component parts. Fig. 5 is a detail perspective view of one of the segment members for cooperating with the fork. F t3 is also a detail perspective view of one of the segment members looking at the side of the same opposite that illustrated by Fig. 5. Fig. '7 is a. detail perspective view of a locking attachment. which cooperates with the segment.

The cotton seed lintiiig or delinting ma chine 5 may be of aiiy'preferred construc tion and embodies the usual hinged or ele vat-able and depressible breast (3 and comprising the roll box and ribs with which the saw cylinder directly cooperates. The saw cylinder 7 has its shaft 8 mounted at opposite extremities in the usual form of separable boxes or journals D and in order to hold the breast and its components elevated, suitable gravitating catches l() are applied to the upper part of the machine to engage headed studs 10l at opposite ends of the breast, as shown by Fig. l. A brush cylinder 7u is associated with the saw cylinder 7 as usual to remove the lint from the latter cylinder.

In the lower front portion of the legs 11 of the frame a shaft 12 is mounted and has an operating lever 13 of angular form Sccured to one end thereof, as clearly shown by Fig. 1,*the said operating lever being so shaped as to stand close to the machine when in normal position and also to eifect a reliable and positive actuation of the shaft l2 by anoperator. Secured on the shaft 12 adjacent to the inner side of each legis a toothed segment 14, each ofthe segments being provided with a `line of teeth l5 and a cam or bearing edge 16, as yclearly shown-tin detail by Figs. 4.- and 6. Close to thel inner side of each leg a saw cylinder engaging fork 17 is movably mounted and is of the form shown in detail by Fig, 5, this fork comprising van upwardly extending arm 18 with an upper forked extremity 19 to bear against the under side of the shaft 8 Lof the saw cylinder, and a lower body 2O having a longitudinal slot 21 at one side of the cen` ter through which the shaft12 extends, each fork having a free sliding movement over the latter shaft. On the body 20 is a rack 22 having a suitable number of teeth and extending parallel with the slot 21, the said rack 22 standing outwardly from the 'body adj acentl to the inner side edge of the latter, whereas the slot 21 is near the outer side edge of said body. y

The outer side of each fork member is formed vwith a recess or roller depressione23 continuing upwardly into .the arm 18, as shown, and having an upper arcuate edge 24 in the body, said edge having a different arcuate curvature adjacent to the point where it merges into the portion of therecess or depression that extends upwardl into the arm 18, as at 25, for a purposewhic will be' presently explained. A movement controllin roller 26 is mounted on theinner side o each leg and extends into t-he recess or depression 23, the depth of the latter being equal to the thickness of the roller so that the roller is inclosed by the leg member and always retained in the recess or depression 23. A guide roller 27 is also mount.

ed on thel inner side 'of each leg and its function isY to direct ,the arm 18v-initsupward movement and conjointly 'coperate with the roller 26 to maintain the fork member inplace during the elevation and depression of said member so that the fork 19 will always be brought to bear Vwith accuracy against the un er side of the shaft of the saw cylinder 7to elevate and throw the latter outwardly-and alsoto direct the movement of the `f orlr when vreplacing the saw cylindervand toeiect an accurate re1- setting of the fork in normal position when the cylinder is4 replaced without imposing undue st-rain on the lower portion of the fork member, especially on the segment 17 and the rack 22 which are always in mesh. It will be understood that the teeth of the rack and of the segment are heavy enough to withstand considerable weight pressure, and

through the medium of ther segment the fork israised and lowered. Secured to thesupper terminal of the .rack 22 andthe body .20 of r the fork member is a locking device comd50-sof the rack andextending through the Aprising a -spindle or pin 28 freely movable in an opening 29 formed in' the upperbegd 0 y 20, the saidvspindl'e or spin 28 having a lock# ing dog 30 on the 'inner end thereof and a .trip arm or projection. 31 on the out-er end,

the said trip armor projection being located within the lower portion of the recess 23 and housed or inclosedby the i'ork member. 'l he dog 30 and trip arm 31 respectively project below and above the spindle or pin 28 and the dog is set in locking position by the roller 26 when the latter4 comes into that portion of the recess 23 which is formed in the body 20 and at the ltime that the upper curved wall 24 of said recess moves over the roller. The dog 30 is so arranged that it will engage the cam or bearing edge 16 of `the segment land lock the latter when the saw cylinder is completely elevated and thrown outwardly and at this time the trip held firmly for the reason that the greater weight or 'portion of the trip arm Awill be outward or past the axis of its movement, said axis being the shaft 12. vThis engagement of the trip arm 31 b the roller 26 takes place when -the fork as reached its segmentV against movement or prevents it nate portion, thearm 31 is tripped an disengages the dog 30 from the cam or bearing operate with the teeth of the rack 22 and gradually lower the ork member, vVhen the fork or arm carrying the saw cylinder is raised by the toothed segment 14, the said fork or. arm cannot rotate outwardly tothe position shown in full lines bit/Fig. 3 unt-il or so that theroller 26 will pass-the point ,of intersection of the innermost wall of the 24, and as' this point o intersect-ion of the or depression 23 has a different arcuate contour from the said edge '24 as hereinbefore noted, the'dogO wil clear of the teeth in -the segment 14, but the dog 30 will not ,take the position shown in carrying both the dog and 'cylinder has been -tinued rotative movement of the shaft 12, Ias shown in full lines in Fig. 8, and-until.v the roller 26 has come in contact with the fork orarm 31 attachedto the dog 30, and through said operation of the roller 26 Athe doo' 30 is forced into the position shown in highest elevation'and the dog 30- loeks theV from becoming disengaged IO1Ltl1eV rack,y

the toothedv segment 34 has raised suiciently recess or depression 23 with the arcuate edge arcuate .edge 24 and inner wall of the recess be caused to swing,

full lines in Fig. B' until the' fork or armA tulrlinos in" Fig. 3 or' in locking engagementA 'arm 31 will be engaged by the roller 26 and when the'said roller strikes thisbearin .arc-

edge 16 andl permits the segment teeth 15 to" rotated to its'outward position by thefconthe upper outer pcrtion of thev cam cr 1go bearing edge 16. 0n returning the saw cylinder into place by means ot the foregoing mechanism the dog 30 remains in the position shown in full lines in Fig. 3 with relation to the fork or arm engaging the cylinder and the Atoothed segment leluntil the roller 26 strikes or engages the intersecting point 25 between the arcuate edge Q-/l and the inner wall of the recess or depression 23, and when the said roller reaches this position the :t'ork or arm will be slightly lifted and the dog 30 thereby released and immediately swing by gravity into the position shown by full lines in F ig. 2 and permitting the fork oi arm, together with the rack, to be depressed and finally restored to normal position by the continued operation of theshaft 12 in an outward direct-ion and at the same time lower the saw cylinder shaft or spindle to its bearings and permit the roll box, including the breast, to be depressed and become engaged with the upper end of the lever 33, as shown in full lines by Fig. 2. This particular operation takes place uniformly adjacent to each leg 11 of the machine and by this means the opposite shaft extremities of the saw cylinder are equally raised and lowered and when the fork members are lowered tbe rollers 26 on each leg 11 moves upwardly into those portions of the recesses Q3 projecting longitudinally of the arms 18 of the said fork members.

Near the center of the shaft 1Q a knuckle joint is fixed and comprises a lever arm 32, to the outer end of which a shorter knuckle arm is pivotally att-ached and limited in its outward movement by a shoulder or pro jecl'ion at thc outer side of the upper end of the lever arm 3QR the outer end of the knuckle arm 33 having a spherical or ball terminal 35 and socket member 36 se cured to the rilorail 37 of the breast 6 of the machine. When the operating or hand lever 13 pulled forward about thirty de grecs this knuckle joint straightens out and lifts the breast, including the ribs, away from the saw cylinder, as shown by Fig. 2, so as to clear these parts of the machine from the saw cylinder preliminary to the movement of the latter in a manner which will be more fully hereinafter explained. The stop shoulder or projection 34 on the outer upper portion of the lever arm 32 prevents the knuckle arm Il?) troni beingdepressed below a right angle relatively to thcl lever arni 3Q so that the knuckle arm is always in position to insure its positive operation or straightening out movement relatively to the said lever arm for the purposes specified.

The mechanism just explained tor removing'r," and replacing the sau' cylinder of a cotton seed liuting or dclinting machine may also be utilized for exposing the saw cylinder' without removing the same, and

for this purpose the operating or hand lever 13 is pulled outwardly so as to turn the shaft through about thirty degrees, this movement of the shaft causing the forks 17 at each end to rise until the upper forked terminals 19 just touch the collars of the saw cylinder7 and this movement also throws open the breast through the medium of the knuckle joint and thereby clears the saws and exposes the latter for any purpose that may be desired. lf the removal of the saw cylinder' is required, the opposite extremities of the saw cylinder shaft'are released by opening the bearing devices therefor and the lever 13, together with the shaft 12, is then pulled outwardly sixty additional degrees or `the lever is caused to move through a total arc of ninety degrees, which will lift the saw cylinder clear of its bearings and permit it to be swung outwardly, as shown by F ig. 3, over a saw cylinder truck ordinarily used for handling saw cylinders, and when another similar truck containing a cylinder is brought into position relatively to the machine, the cylinder thereon may then be caused to engage the upper forked extremities 19 and the fork membeys thrown back and finally lowered to dispose the substitute cylinder in the bearings therefor. This work may be carried on solely by one operative. Vlvhen the breast is raised to the full operating extent of the knuckle joint, it is further elevated by hand, and it will be understood that the gravity hooks 10 cooperate with thc breast, by catching over the ystuds on the ends ot' the breast casting and lprior to lowering the fork members the breast will be released by disengaging the hooks therefrom. e

The segments 11 practically operate as pinions and it would not require any variation of the invention to use complete pinions instead of these segments, but as only a portion of the teeth of the complete pinion would operate with the racks it has been found that thetscgments as shown serve the purpose of the intermediate motion -transmitting means between the shaft and the racks and are more advantageous. The lifting fork members are not effective while the hand lever is moving forwardly through the first thirty degrees from its normal position. This preliminary movement. of the hand lever operates to raise the breast and ribs clear of the saws1 but such preliminary movement of the hand lever brings the liftingl fork members up to suoli position that any further travel or outward movement of the hand lever will tend to lift the saw cylinder out of place. During this preliminary movement the roller 2G does not become disengaged from the portion of the recess 23 extending upwardly into each lifts ing fork member, and only when the second outward thi rty-degree movement of the hand 35 dition, and. further,

55 and mote board may lever is eiected does the said roller pass into the lower enlarged ortion of the recess 23 and each fork will t en be in condition for swinging outwardly to deposit the saw cylinder carried thereby on the usual cylinder ltruck or any other device, as may be desired. wWhen releasing the locking means 'and at the time when the roller strikes the different arcuate portion of the upper edge 24 of the recess in the body 20 of the fork member, the forlrmelnber free to be slightly raised to release the loelrand thel lock swings outof the way by gravity.'

The improved attachment will he ound v3 5 exceptionally advantageous in that it is unnecessary to remove bolts and nuts to open the bearings, the bearings used being preferably of the clamp screw and hinge lid type which can be easily manipulated to release the opposite extremities of the saw cylinder' shaft and. the single lever then operated to remove the cylinder. Furthermore, by supporting the breast on the catch hooks as explained/the necessity of dismounting and removing the breast is avoided and the im roved attachment ormeans for lifting -an remo-ving the'saw cylinder also dispenses with the use of the ordinary form of cylinder hoist'v and also the Work of 3o extra operatives. By eliminating these various disadvantageous features, a cotton seed linting or delinting machine may he more conveniently manipulated, such for'instance as keeping the saws sharp and in good coninjury to operators by the saw cylinders during the operations ot' removing and replacing or resetting said 'cylinders is prevented.

The motingboard organization also em- 40 bodying features of the improvemnt 'comprises a main moting board 88 hin ed as at 39. At the free extremity of the card 88 is adepending member 40 vhinged at 'el to the board to accommodate various angles of the latter when adjusted, and on the said member is secured a rack 42- meshing with a. pinion i8 on the inner end of a shaft 44 having bearinY in one of the legs 1l. The shaft la exten s through the leg 1l and has an operating arm 45 attached to its outer 50 the mote board 38 as may be desired. 1n

the Jfree extremity of the mote board 88, slots 9 are formed and therethrough ad- "justaloly extend hcltsbO having their low'er headed 'ends bearing against the nnder side 8E of the mote board and their upper screw-A threaded ends 51 engaging liXed nuts .or sleeves 52 mounted in a base 53 of a mote board extension 54, the latter consisting of a hollow sheet metal body `with an outer straight wall 55 and an inner arcuate wall 56, the walls 55 andY 56 intersecting at their upper edges in a point- 57 movable upwardly and downwardly between the saw cylinder 1? and brush cylinder 72. The mote board extension 5a serves as a deector and the metes pass downwardly over or between the inner arcuate Wall 56 and the brush cylinder 7 to the main mote board 38, the inner terminal ot' the base 53 being beveled or reduced in a curved plane corresponding to that of the inner Wall 56, as at 58. The 'ase 53 and the hollow sheet metal hody 54 constitnting the mote board extension is adjustable inwardly and outwardly over the outer or free extremity of the mote board 38 through the medium of the bolts 50 moving in the slots 49, such adjustment of the mote hoard extension being independent ci? the adjustment of the mote hoard as a whole, as hereinhefore explained. When the mote board 38 is raised and lowered the extension moves similarly therewith, and to adjust the 4 mote hoard extension inwardly and out wardly over the mote board 38 a connecting rod 59 has its outer screw-threaded extremity 60 inserted through an opening or eye" 6l on the lower end or head of the innermost bolt 50, the screw-threaded extremity GO of the rod 59 being adjustable inthe said eye to preliminarily set the mote board err# tension 54 as may he desired relatively'to the main mote board 38, and to maintain the,- adjustin'ent, nuts 62 and 68 engage the screw-tlneaded extremity @dei the r'cd 59 and operate as set nuts relatively to `the lower extremity or head of the innermost bolt 50. it is preferred that the lower and of the innermost bolt 50 he slightly flattened as shown so as to facilitate the formation of the eye Gl therethrough, lent such construction will not in the. least defeat its function ,in serving' as a hearing means against the under side of the main mote board 38, suitable washers being interposed between the lower or headed ends of the bolts 50 and the under side of the said moteboard 38. The rear end of the rod 59 is connected to a crank armll projecting from a shaft 65 extendin .through the leg llgof the machine and aliso having attached thereh to an operating arm G6 associated with asegmen't G? having a segmental slot 68 which is engaged by a clamping screw or analogous device G9 carried by the outer end of the arm 6G to maintain the adjustment ofthe rod 59 and the mote board extension 54; on the main mote board 88. lt will he under stood that the movement o the arm 66 in` opposite directions will correspondingly move the rod 59 and 'shift the mote board .uw

extension 5t on the main mote board 38 either inwardly or outwardly in accordance with the direction of movement of the said operating arm G6. By shifting the mote board extension 54 on the mote board 38 the inner concave wall 36 may be broughtcloser to or shifted outwardly from the brush cylinder 7a and likewise be brought closer to or farther away from the saw cylinder, and, furthermore, the point 5f of the mote board extension may be elevated or depressed and the various conditions attending the ginning of different kinds of seed cotton may be met to the best advantage and a more effective operation relatively to the lint may be performed so that the lint may be made as clean as desired. The mote board 38 and extension 5-1 work in conjunction with the seal board depending from the top frame of the machine between the caw cylinder 7 and brush cylinder 7, said 'seal board having its lower end reduced and extending' downwardly closely between the two cylinders.
